Remember to follow PEMDAS, and left -> right rule.
First, solve the Parenthesis:
(4 + 2^3)
Solve the exponent.
2^3 = 2 x 2 x 2 = 4 x 2 = 8
4 + 8 = 12
_______________________________________________________________
(5^2) x (12)
5^2 = 5 x 5 = 25
25 x 12
_______________________________________________________________
Multiply
25 x 12 = 300
________________________________________________________________
300 is your answer

Answer:
circumference: 37.7
area: 113.1
Step-by-step explanation:
for the future look up '___ of a circle'
and enter the radius (if u are given the diameter divide it by 2)
The cosine of A is (adjacent side)/(hypotenuse) = 55/73. Do the division, then find the angle whose cosine is that number. The whole thing takes maybe 6 or 7 seconds with your calculator. It's choice-B.
